Duckweed is a potential collector of nitrogen from animal liquid manure and source protein suitable as feed for livestock fish. Therefore, it provides opportunities circular economy systems. Two duckweed species, Spirodela polyrhiza Landoltia punctata, were grown in five recirculating systems each connected to reservoir tank filled with water graded organic cattle slurry concentrations. Fresh dry biomass, production amino acid profiles among the removal evaluated. showed significantly higher...
Two four-week feeding trials were conducted with fingerlings of Eurasian perch (Perca fluviatilis, 3.52 ± 0.08 g) and rainbow trout (Oncorhynchus mykiss, 1.49 0.05 fed graded levels dried (DWD) fermented (DWF) duckweed meal (Spirodela polyrhiza). The purpose these two was to evaluate DWD DWF as replacements for fishmeal. Fishmeal protein substituted by 12%, 24%, 35% compared control diets containing 40% (for perch) trout) fishmeal no duckweed. performance the fish (growth, feed conversion,...
The rearing of less established fish species in recirculating aquaculture systems (RASs) is increasing, but may require adaptations the facilities if health impairments occur. We observed several issues burbot Lota lota reared for up to 2 yr a RAS and used microbiological, histological molecular-biological methods identify causative agents. Minor skin trauma led development ulcers. In addition, fillets showed pronounced granulomatous inflammation calcification with signs muscle fiber...
